Hi Guys
I'm now dosing EI salts to my 300lts/ 80 gal planted tank by using the on-line calculator at https://www.thenutrientcompany.com/aquarium/calculators/ei_calculator/.
It say to dose 2 teaspoons of Magnesium Sulphate (MgSO4) for 3 times a week.
That's a total of 6 teaspoons per week.
Now I have seen at the Barr Report
http://www.barrreport.com/forum/bar...ndex/2938-ei-light-for-those-less-techy-folks
There is no mention of Magnesium Sulphate dosing separately.
Instead Magnesium Sulphate is dosed as part of GH booster.
GH Booster is composed of :
1 part magnesium sulfate,
3 parts potassium sulfate and
3 parts calcium sulfate.
In the Barr Report website it mentions to dose
+/- 1 teaspoon once a week (water change only) for 60 to 80 gal tank.
So according to Tom Barr website, magnesium is dosed one seventh part of a teaspoon.
That's several times less. ( maybe some one will be kind enough to do the maths for the exact percentage)
Now, I ask why the vast difference between 6 teaspoons a week and less than 1/7th of a teaspoon a week?
Is there a calculation error?
BTW. My tape water ph is 6.8
Thank you very much.
